Naphthenes

Naphthenes

alicyclic alkanes primarily found in petroleum (hence their name, which was first introduced in organic chemistry in 1883 by V. V. Markovnikov and V. N. Ogloblin). The most important naphthenes are cyclopentane and cyclohexane and their alkyl derivatives. Hydrocarbons containing several five- and six-member rings (including condensed forms such as Decalin) are also classified as naphthenes. However, some authors incorrectly expand the class to cover all cycloalkanes (cyclanes).

Breen et al [3] and Seo et al [19] analyzed the liquid products obtained from the catalytic degradation of HDPE using GC-MS and found that the products were mainly consisted of paraffins, olefins, naphthenes and aromatics (PONA) where the detailed composition of the products has not been mentioned.
